// A FileDiskRep represents a single code file on disk. We assume nothing about
// the format or contents of the file and impose no structure on it, other than
// assuming that all relevant code is contained in the file's data bytes.
// By default, we seal the entire file data as a single page.
//
// This is the ultimate fallback disk format. It is used if no other pattern
// applies. As such it is important that we do not introduce any assumptions
// here. Know that you do not know what any of the file means.
//
// FileDiskrep stores components in extended file attributes, one attribute
// per component. Note that this imposes size limitations on component size
// that may well be prohibitive in some applications.
//
// This DiskRep does not support resource sealing.
